### 1184: Circumference Formula - explain xkc

1. Explanation. The circumference C of a circle is 2 π r, where r is the radius of the circle. Randall then makes a footnote about r, using 2. This creates a typographical ambiguity, since a superscript 2 can also be an exponent (as in x2 ). The comical purpose of this ambiguity is that the formula initially makes an appearance of a mistake and.
2. Doesn't seem like it. These equations actually do look like the kinds of equations you would see in these fields. On blackboards in movies you tend to get equations that are pure nonsense. 172.68.143.132 (please sign your comments with ~~~~) pure = clean -> sheer = absolute Lysdexia 01:42, 5 January 2019 (UTC
3. Using a formal solver with symbolic, numeric, or both methods requires making sure that the constraints (e.g. equations) are entered correctly, with parentheses balanced in their correct locations for the solution to succeed
4. The last line takes the formula distance = 1/2 a t² from physics and plugs it into the equation of the previous line, doing some algebra to replace a t² with distance2 and expanding (na)² into nana to get the final equation, distance2banana = b³/θ²

Friis, is either of two formulas used in telecommunications engineering to calculate the signal-to-noise ratio of a multistage amplifier.One relates to noise factor while the other relates to noise temperatur Gravity (from Latin gravitas 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light —are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides.The gravitational attraction of the original gaseous matter present.

For nonpolynomial equations and systems without symbolic parameters, the numeric solver returns only one solution (if a solution exists). If solve cannot find a solution and ReturnConditions is true , solve returns an empty solution with a warning The Distance Formula is a variant of the Pythagorean Theorem that you used back in geometry.

Solve quadratic equations using a quadratic formula calculator. Calculator solution will show work for real and complex roots. Uses the quadratic formula to solve a second-order polynomial equation or quadratic equation. Shows work by example of the entered equation to find the real or complex root solutions Differential equations in this form are called Bernoulli Equations. First notice that if $$n = 0$$ or $$n = 1$$ then the equation is linear and we already know how to solve it in these cases. Therefore, in this section we're going to be looking at solutions for values of $$n$$ other than these two

Simple explanations of the sometimes complicated nerd comic xkcd.co Equations of nonconstant coefficients with missing y-term If the y-term (that is, the dependent variable term) is missing in a second order linear equation, then the equation can be readily converted into a first order linear equation and solved using the integrating factor method Word problems with linear equations (that is, with straight-line models) almost always work this way: the slope is the rate of change, and the y-intercept is the starting value.(I can't, off the top of my head, think of any instance in which this would not be the case. If I shot an infinitely strong laser beam into the sky at a random point, how much damage would it do? Garrett D.

Answers is the place to go to get the answers you need and to ask the questions you wan Section 3-1 : The Definition of the Derivative. In the first section of the Limits chapter we saw that the computation of the slope of a tangent line, the instantaneous rate of change of a function, and the instantaneous velocity of an object at $$x = a$$ all required us to compute the following limit. \[\mathop {\lim }\limits_{x \to a} \frac{{f\left( x \right) - f\left( a \right)}}{{x - a}}\ ‪Balancing Chemical Equations� In a follow-up, we'll learn about graphing, complements, and using Euler's Formula to find even more connections.

The pessimist is probably more right about how it turns out than the optimist. When people say glass half empty, they usually mean something like a glass containing equal parts water and air: Traditionally, the optimist sees the glass as half full while the pessimist sees it as half empty.
